Description

Technical Field

[0001] This utility model relates to the field of educational toy technology, and in particular to a magnetic positioning magic watch. Background Technology

[0002] Traditional magic watches use springs and raised dots on plastic parts to position each scale, which has the disadvantages of high resistance, low accuracy, and poor feel.

[0003] Therefore, there is an urgent need for a product that can solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems of existing magic watches, such as high resistance, low accuracy, and poor feel.

[0005] To solve the above-mentioned technical problems, this utility model provides a magnetic positioning magic watch, which adopts the following technical solution:

[0006] The magnetic positioning magic watch includes a dial, several driving wheels, several driven wheels, and several transmission wheels. The driving wheels and the driven wheels are all located inside the dial. A portion of each driving wheel extends out from the side of the dial. The transmission wheels are movably inserted through the dial to control the transmission connection between the adjacent driving wheels and the driven wheels.

[0007] The front of the dial is provided with a plurality of dials, each of which is provided with a drive wheel or a driven wheel. The front of the drive wheel and the driven wheel near the front of the dial are provided with pointers. The scale ring of the dial is provided with a first magnetic attractor. Each tooth of the drive wheel and / or the driven wheel is provided with a second magnetic attractor that attracts the first magnetic attractor.

[0008] Optionally, the teeth of the driving wheel and / or the driven wheel are provided with mounting holes, and the second magnetic member can be disposed in the mounting holes.

[0009] Optionally, the driving wheel and / or the driven wheel have twelve teeth, and each tooth is provided with the second magnetic attractor.

[0010] Optionally, the dial has two first magnetic elements at the scale ring, and the line connecting the two first magnetic elements passes through the center of the dial.

[0011] Optionally, both the first magnetic attractor and the second magnetic attractor are original sheet magnets, and they are opposite magnetic poles to each other;

[0012] Alternatively, one of the first magnetic attractor and the second magnetic attractor may be the original magnet, and the other may be an iron sheet.

[0013] Optionally, the back of the dial is provided with a plurality of dials, and each dial on the back of the dial is provided in a one-to-one correspondence with each dial on the front of the dial.

[0014] Optionally, both the back of the driving wheel and the driven wheel near the back of the disc are provided with pointers.

[0015] Optionally, two driven wheels are stacked between two dials that are correspondingly arranged on the front and back of the dial.

[0016] Optionally, the front of the dial is provided with a plurality of magnetic rings, each of the transmission wheels is inserted through a corresponding magnetic ring, and a third magnetic element is provided inside the transmission wheel that can attract the magnetic ring.

[0017] Optionally, a plurality of magnetic rings are provided on the back of the dial, and each magnetic ring corresponds one-to-one with each magnetic ring on the front of the dial.

[0018] Compared with the prior art, the magnetic positioning magic watch provided by this utility model has the following advantages:

[0019] The front of this magnetic positioning watch features several dials, each with either a drive wheel or a driven wheel. A first magnetic element is located at the scale ring of each dial, and each tooth of the drive and driven wheels contains a second magnetic element that attracts the first magnetic element. As the drive wheel (or driven wheel) rotates, the second magnetic elements on the teeth of the drive wheel (or driven wheel) that were initially attracted to the first magnetic element on the corresponding dial gradually detach from the first magnetic element, and the attraction between them gradually decreases. Simultaneously, the next tooth gradually approaches the first magnetic element, and the attraction between the second magnetic element and the first magnetic element on the next tooth gradually increases. This effectively reduces the rotational resistance of the drive wheel (or driven wheel), resulting in a better feel when rotating. When the second magnetic element on the next tooth attracts the first magnetic element, the drive wheel (or driven wheel) is stationary relative to the dial, and its pointer accurately points to the corresponding scale on the dial.

"A plurality of" means two or more, unless otherwise explicitly specified.

[0033] In the description, claims, and accompanying drawings of this utility model, when an element is referred to as "fixed to," "mounted to," "set on," or "connected to" another element, it can be directly or indirectly located on that other element. For example, when an element is referred to as "connected to" another element, it can be directly or indirectly connected to that other element.

[0034] Furthermore, the reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] This utility model embodiment provides a magnetic positioning magic watch 100, such as Figures 1 to 6 As shown, the magnetic positioning magic watch 100 includes a dial 10, several driving wheels 20, several driven wheels 30, and several transmission wheels 40. The driving wheels 20 and driven wheels 30 can both be located within the dial 10. A portion of each driving wheel 20 can extend from the side of the dial 10, allowing the user to rotate the driving wheel 20 by turning the extended portion. The transmission wheels 40 are movably mounted on the dial 10 to control the transmission connection between adjacent driving wheels 20 and driven wheels 30.

[0036] Understandably, the drive wheel 40 can move relative to the dial 10 so that when the drive wheel 20 rotates relative to the dial 10, the driven wheel 30 remains stationary relative to the dial 13, that is, when the drive wheel 20 is turned, only the drive wheel 20 rotates; or, when the corresponding drive wheel 20 rotates relative to the dial 10, each driven wheel 30 connected to the drive wheel 40 also rotates synchronously, that is, when the drive wheel 20 is turned, each driven wheel 30 that has a transmission relationship with the drive wheel 20 also rotates accordingly.

[0037] The front 11 of the dial 10 may be provided with a plurality of dials 13, and each dial 13 may be provided with a driving wheel 20 or a driven wheel 30. The front 11 of the driving wheel 20 and the driven wheel 30 near the front 11 of the dial 10 may be provided with pointers 22 and 32. The scale ring 131 of the dial 13 may be provided with a first magnetic attractor 132, and each tooth 21 and 31 of the driving wheel 20 and / or the driven wheel 30 may be provided with a second magnetic attractor (not shown in the figure) that attracts the first magnetic attractor 132.

[0038] Optionally, each tooth 21 of the drive wheel 20 is provided with a first magnetic element 132. When the drive wheel 20 rotates for adjustment, the second magnetic element in each tooth 21 of the drive wheel 20 cooperates with the first magnetic element 132 at the corresponding dial 13, so that its pointer 22 can accurately point to each scale of the scale ring 131 around the corresponding dial 13. The drive wheel 20 can drive each driven wheel 30 that has a transmission relationship to it to rotate, so that when the driven wheel 30 rotates for adjustment, its pointer 22 can also point to each scale of the scale ring 131 around the corresponding dial 13 with relatively high accuracy.

[0039] Alternatively, each tooth 31 of the driven wheel 30 is provided with a first magnetic element 132. When the driving wheel 20 rotates to drive the driven wheel 30 which has a transmission relationship to adjust, the second magnetic element in each tooth 31 of the driven wheel 30 cooperates with the first magnetic element 132 at the corresponding dial 13. The pointer 32 of the driven wheel 30 can accurately point to each scale of the scale ring 131 around the corresponding dial 13. The driving wheel 20 which has a transmission relationship with the driven wheel 30 can also have its pointer 32 pointing to each scale of the scale ring 131 around the corresponding dial 13 with relatively accurate accuracy through the coordinated action.

[0040] Alternatively, each tooth 21, 31 of the driving wheel 20 and the driven wheel 30 is provided with a first magnetic element 132. When the driving wheel 20 rotates for adjustment, the second magnetic element in each tooth 21 of the driving wheel 20 cooperates with the first magnetic element 132 on the corresponding dial 13, so that its pointer 22 can accurately point to each mark on the scale ring 131 around the corresponding dial 13. At the same time, when the driving wheel 20 rotates to drive the driven wheel 30 which has a transmission relationship for adjustment, the second magnetic element in each tooth 31 of the driven wheel 30 cooperates with the first magnetic element 132 on the corresponding dial 13, so that the pointer 32 of the driven wheel 30 can accurately point to each mark on the scale ring 131 around the corresponding dial 13.

[0041] Understandably, the working principle of the first magnetic component 132 and the second magnetic component of the magnetic positioning magic watch 100 working together is roughly as follows:

[0042] When the driving wheel 20 (or driven wheel 30) of the magnetic positioning magic watch 100 rotates, the second magnetic elements on the teeth 21, 31 of the driving wheel 20 (or driven wheel 30) that were originally attracted to the first magnetic element 132 of the corresponding dial 13 gradually detach from the first magnetic element 132, and the attraction between the two gradually decreases. At the same time, the next teeth 21, 31 gradually approach the first magnetic element 132, and the attraction between the second magnetic element of the next teeth 21, 31 and the first magnetic element 132 gradually increases, which can effectively reduce the rotational resistance of the driving wheel 20 (or driven wheel 30). When the second magnetic element of the next teeth 21, 31 attracts the first magnetic element 132, the driving wheel 20 (or driven wheel 30) is stationary relative to the dial 13, and the pointers 22, 32 on it can accurately point to the corresponding scale on the dial 13.

[0043] In summary, compared with existing technologies, the magnetic positioning magic watch 100 has at least the following beneficial effects:

[0044] The front 11 of the dial 10 of the magnetic positioning magic watch 100 is provided with several dials 13. Each dial 13 is provided with a driving wheel 20 or a driven wheel 30. The scale ring 131 of the dial 13 is provided with a first magnetic attracting element 132. Each tooth 21, 31 of the driving wheel 20 and the driven wheel 30 is provided with a second magnetic attracting element that attracts the first magnetic attracting element 132. When the drive wheel 20 (or driven wheel 30) rotates, the second magnetic elements on the teeth 21, 31 of the drive wheel 20 (or driven wheel 30) that were originally attracted to the first magnetic element 132 of the corresponding dial 13 gradually detach from the first magnetic element 132, and the attraction between the two gradually decreases. At the same time, the next teeth 21, 31 gradually approach the first magnetic element 132, and the attraction between the second magnetic element of the next teeth 21, 31 and the first magnetic element 132 gradually increases, which can effectively reduce the rotational resistance of the drive wheel 20 (or driven wheel 30), thereby making the rotation feel better. When the second magnetic element of the next teeth 21, 31 attracts the first magnetic element 132, the drive wheel 20 (or driven wheel 30) is stationary relative to the dial 13, and the pointers 22, 32 on it can accurately point to the corresponding scale on the dial 13.

[0045] To enable those skilled in the art to better understand the present invention, the following will be described in conjunction with the appendix. Figures 1 to 7 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the magnetic positioning magic watch 100 also includes a housing 50, with the dial 10 disposed inside the housing 50 and partially protruding from the side of the housing 50, allowing the user to rotate the drive wheel 20 by turning the protruding portion. A transmission wheel 40 can be inserted into the housing 50. Furthermore, the housing 50 can be made of a transparent material.

[0047] In some embodiments, such as Figure 4 and Figure 5 As shown, mounting holes 211 and 311 can be provided on the teeth 21 and 31 of the driving wheel 20 and / or driven wheel 30, and the second magnetic member can be engaged in the mounting holes 211 and 311. The mounting holes 211 and 311 can pass through the side of the teeth 21 and 31 facing the dial 13, so that when the second magnetic member and the first magnetic member 132 are attracted, there is no obstruction between them, ensuring that there is sufficient attraction between them.

[0048] Optionally, if each tooth 21 of the driving wheel 20 is provided with a first magnetic attractor 132, then each tooth 21 of the driving wheel 20 is provided with a mounting hole 211. Alternatively, if each tooth 31 of the driven wheel 30 is provided with a first magnetic attractor 132, then each tooth 31 of the driven wheel 30 is provided with a mounting hole 311. Or, if each tooth 21, 31 of both the driving wheel 20 and the driven wheel 30 is provided with a first magnetic attractor 132, then each tooth 21, 31 of both the driving wheel 20 and the driven wheel 30 is provided with a mounting hole 211, 311.

[0049] In some embodiments, such as Figure 4 and Figure 5 As shown, the driving wheel 20 and / or driven wheel 30 may have twelve teeth 21, 31, and each tooth 21, 31 may be provided with a second magnetic element. Understandably, the dial 13 has twelve graduations 131, with each graduation spaced 30° apart. Correspondingly, the driving wheel 20 and / or driven wheel 30 have twelve teeth 21, 31, also spaced 30° apart. When the driving wheel 20 and / or driven wheel 30 rotates 30°, the second magnetic element in the tooth 21, 31 overlapping with the first magnetic element 132 of the corresponding dial 13 can attract the first magnetic element 132. At this time, the pointers 22, 32 on the driving wheel 20 and / or driven wheel 30 can accurately point to the corresponding graduation.

[0050] Optionally, the driving wheel 20 has twelve teeth 21, each of which may be provided with a second magnetic element, and the corresponding dial 13's scale ring 131 also has twelve scales; or, the driven wheel 30 has twelve teeth 31, each of which may be provided with a second magnetic element, and the corresponding dial 13's scale ring 131 also has twelve scales; or, both the driving wheel 20 and the driven wheel 30 have twelve teeth 21, 31, each of which may be provided with a second magnetic element, and the corresponding dial 13's scale ring 131 also has twelve scales.

[0051] Of course, the number of teeth 21 and 31 on the driving wheel 20 and / or driven wheel 30 can also be set to other numbers, such as two or four, as long as the number of teeth 21 and 31 on the driving wheel 20 and / or driven wheel 30 corresponds to the number of graduations on the corresponding dial.

[0052] In some embodiments, such as Figure 3 As shown, two first magnetic attractors 132 may be provided at the scale ring 131 of the dial 13. The line connecting the two first magnetic attractors 132 may pass through the center of the dial 13 so that when the two first magnetic attractors 132 attract the corresponding two second magnetic attractors, the rotation of their driving wheel 20 and / or driven wheel 30 can be better restricted.

[0053] In some embodiments, as an implementation of the first magnetic attractor 132 and the second magnetic attractor, both the first magnetic attractor 132 and the second magnetic attractor can be original magnetic sheets, and they are opposite magnetic poles, so that the two original magnetic sheets can attract each other.

[0054] In some embodiments, as another implementation of the first magnetic attractor 132 and the second magnetic attractor, one of the first magnetic attractor 132 and the second magnetic attractor is a solid magnet, and the other is an iron sheet, so that the iron sheet can be attracted to the solid magnet. Specifically, the first magnetic attractor 132 is a solid magnet, and the second magnetic attractor is an iron sheet; or, the first magnetic attractor 132 is an iron sheet, and the second magnetic attractor is a solid magnet.

[0055] In some embodiments, the back surface 12 of the dial 10 may be provided with a plurality of dials 13, and each dial 13 located on the back surface 12 of the dial 10 may be provided in a one-to-one correspondence with each dial 13 located on the front surface 11 of the dial 10. The arrangement of the first magnetic member 132 at each dial 13 on the back surface 12 of the dial 10 is the same as that on the front surface 11 of the dial 10, and will not be described again here.

[0056] In some embodiments, pointers 22 and 32 may be provided on the back side 12 of the drive wheel 20 and the driven wheel 30 near the back side 12 of the dial 10. The arrangement relationship between the back side 12 of the drive wheel 20 and the driven wheel 30 near the back side 12 of the dial 10 and the dial 13 corresponding to the back side 12 of the dial 10 is the same as the arrangement relationship between the front side 11 of the drive wheel 20 and the driven wheel 30 near the front side 11 of the dial 10 and the dial 13 corresponding to the front side 11 of the dial 10, and will not be described again here.

[0057] In some embodiments, when two dials 13, which are correspondingly arranged on the front 11 and back 12 of the dial 10, are both configured as driven wheels 30, the two driven wheels 30 can be stacked to form a group of driven wheels 30. When the driving wheel 20 has a transmission relationship with any driven wheel 30 in an adjacent group of driven wheels 30, the rotation of the driving wheel 20 can drive the driven wheel 30 of that group of driven wheels to rotate.

[0058] Specifically, in some embodiments, when both the front 11 and the back 12 of the dial 10 are provided with corresponding dials 13, and a drive wheel 20 is provided between two corresponding dials 13, there is one drive wheel 20. Both the front 11 and the back 12 of the drive wheel 20 are provided with pointers 22. The pointer 22 on the front 11 of the drive wheel 20 points toward the dial 13 on the front 11 of the dial 10, and the pointer 22 on the back 12 of the drive wheel 20 points toward the dial 13 on the back 12 of the dial 10.

[0059] When two corresponding dials 13 are configured with a set of driven wheels 30, the pointer 32 on the driven wheel 30 near the front 11 of the dial 10 corresponds to the dial 13 on the front 11 of the dial 10, and the pointer 32 on the driven wheel 30 near the back 12 of the dial 10 corresponds to the dial 13 on the back 12 of the dial 10.

[0060] When the drive wheel 40 moves toward the front 11 of the dial 13, the drive wheel 40 meshes with its corresponding drive wheel 20, and the drive wheel 40 meshes with the driven wheels 30 in each group of driven wheels 30 adjacent to the drive wheel 20 that are close to the front 11 of the dial 10, so that the drive wheel 20 has a transmission relationship with the aforementioned driven wheels 30, so that when the drive wheel 20 is turned, it can drive the driven wheels 30 that have a transmission relationship with it to turn, so that the corresponding pointers 22, 32 located on the front 11 of the dial 10 will turn. Conversely, when the drive wheel 40 moves toward the back surface 12 of the dial 13, the drive wheel 40 meshes with its corresponding drive wheel 20, and the drive wheel 40 meshes with the driven wheels 30 in each group of driven wheels 30 adjacent to the drive wheel 20 that are close to the back surface 12 of the dial 10, so that the drive wheel 20 has a transmission relationship with the aforementioned driven wheels 30, so that when the drive wheel 20 is turned, it can drive the driven wheels 30 that have a transmission relationship with it to turn, and thus the corresponding pointers 22, 32 located on the back surface 12 of the dial 10 will turn.

[0061] In some embodiments, such as Figure 3 and Figure 6 As shown, a plurality of magnetic rings 14 may be provided on the front surface 11 of the dial 13, and each transmission wheel 40 may be inserted through a corresponding magnetic ring 14. A third magnetic element 41 that can attract the magnetic ring 14 may be provided inside the transmission wheel 40. When the transmission wheel 40 moves toward the front surface 11 of the dial 13, the third magnetic element 41 inside the transmission wheel 40 can attract the corresponding magnetic ring 14 on the front surface 11 of the dial 13, so that the transmission wheel 40 moves into place, ensuring that the transmission wheel 40 can enable the corresponding driving wheel 20 and the driven wheel 30 of each adjacent group of driven wheels 30 that is close to the front surface 11 of the dial 10 to have a stable transmission relationship.

[0062] In some embodiments, such as Figure 3 and Figure 6 As shown, a plurality of magnetic rings 14 may be provided on the back side 12 of the dial 13, each magnetic ring 14 corresponding to one of the magnetic rings 14 on the front side 11 of the dial 13. Two third magnetic elements 41 may be present inside the transmission wheel 40. Each transmission wheel 40 may pass through the corresponding magnetic rings 14 on the front side 11 and back side 12 of the dial 10. When the transmission wheel 40 moves toward the back side 12 of the dial 13, the third magnetic element 41 inside the transmission wheel 40 can attract the corresponding magnetic ring 14 on the back side 12 of the dial 13, thereby moving the transmission wheel 40 into position. This ensures that the transmission wheel 40 can maintain a stable transmission relationship between the corresponding driving wheel 20 and the driven wheel 30 in each adjacent group of driven wheels 30 that is closest to the back side 12 of the dial 10.

[0063] It should be noted that, as Figure 3 and Figure 7 As shown, the solution described in this specification can be applied to various forms of magnetic positioning magic watches, including but not limited to the following: [Combined with...] Figure 3 The magnetic positioning magic table 100 can be an n×n square magic table (such as a 3×3 square magic table); combined with Figure 7 Figure (a) shows that the magnetic positioning magic watch 100 can also be a triangular magic watch; combined with Figure 7 As shown in Figure (b), the magnetic positioning magic watch 100 can also be a pentagonal magic watch, etc.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
